DI-SINFEOTING APPARATUS APPLICABLE TO MANHOLES.

Application filed April 5, 1918.

to provide simplified, eflicient and cheap means for such purpose; and a further object is to partially or wholly destroy germs that escape through -man-h0les or ventilators that are used in connection with such sewerage systems.

According to my said invention, the said apparatus is made to suit any man hole or ventilator of the kind described, and comprises an inner-conical chamber having open ends top and bottom, the smaller open end being at the top and having a fluid containing cap held clear of this smaller open end by means of supporting legs detachably connected to this end portion of said conical chamber. The bottom of this cap is provided with an annular well for containing fluid having a disinfecting nature. Circumferential'ly positioned in the interior and lower and larger end portion of this conical chamber isanother annular well for containing a suitable disinfecting fluid. In or about midway in said conical chamber is a cross-piece or bracket bearing in which is Totatably positioned a collared shaft or pivot having at eachend one or more blades arranged at suitable angles so as to be driven by the draft of air which passes constantly through the man-hole or ventilator, thefree end or ends of the upper blade or blades dipping into the disinfecting fluid in the well in said cap, and the free end or ends of the lower blade or blades dipping into .the lower well, this wind-mill type of apparatus being adapted to constantly agitate the fluid in both wells so that more pronounced odors are given off from. said disinfecting fluid. Over said conical chamber is concentrically placed an outer cylindrical chamber having Specification of Letters Patent.

Patented ca. 22, 1918.

Serial No. 226,823.

its lower end fixed to the lower end portion of said conical chamber so as to form a receptacle or well for containing a suitable disinfecting fluid, the top of this outer chamher being coned and open and provided with a similar fluid containing cap having an annular well for a suitable disinfectant and being supported on and clear of the top of said outer chamber. The inner diameter of annular well of each of said caps is larger than the diameter of the opening over which it is placed.

The apparatus rests in a hanger or container comprising a vertically positioned cylinder with open ends, the lower end having an annular well provided with spaced blocks or rests to receive arms or flanged projections on the lower end of said conical chamber for bolting the latter into said annular well which is filled with water thus making an. airtight joint so that the draft and fumes from the sewer or the like pass up through the conical chamber and out of its top into the outer cylindrical chamber andthence through the opening at the top of the latter to the atmosphere, and at the same time'this draft of foul or impure air is amalgamated or mixed with the odors given off from the disinfectants contained in the annular wells and receptacle herein referred to so that the gases reaching the atmosphere are rid of objectionable smells which are a source of danger to the public health. Said fhanger or container rests in the man-hole or ventilator of the sewer or the like and over such may be positioned the usual man-hole grating so that the inflowing surface water reaches and overflows the annular well in bottom of said container whence it flows into the sewer or the like. In combination with my said'apparatus, I may use any suitable disinfectants or disinfecting fluids for the purposes set forth.

Adjacentto or near to each well or re ceptacle, filling or inspection holes may be made and adjustably covered by means of sliding panels or hinged covers or the like, so that the apparatus may be inspected and the wells filled when desired.

,The said apparatus constructed and arranged in accordance with my said invention is'more fully described hereinafter and is illustrated in the accompanying drawing, and the same reference numbers are used for the same parts throughout.

The drawing shows a sectional elevation of the said apparatus.

The inner conical chamber 1 has an open end 2 and an open top 3, the smaller open end at the top having an annular fluid containing cap 4 held clear of the smaller open end by means of supporting legs such as 5 detachably connected to this end portion of said conical chamber by means of bolts or the like, not shown. The bottom of this cap is provided with an annular well 6 for containing any suitable disinfecting fluids.

Circumferentially positioned in the interior and lower. and larger end portion of this conical chamber is another annular well 7 for containing a similar disinfecting fluid, this annular well being suitably fixed or riveted at 8 to the conical chamber 1. In or about midway in the conical chamber 1 is a cross-piece, or bracket bearing 9 provided perferably with anti friction bearings such .as shown, and in which is rotatably positioned a collared shaft or pivot 10 having fixed at the upper end there of a fan like blade 11 or blades as the case may be, said shaft having at its lower end a similar fan like blade 12, both of which are arranged at suitable angles or pitches so as to be driven by the draft of air which constantly passes through the manhole or ventilator, the free end or ends of the upper blade 11 being bent over at 13 to dip into the disinfecting fluid in the well 6, and the free end or ends of the lower blade or blades 12 being bent at 14 and adapted to dip into the lower well 7, this wind-mill type of apparatus being adapted to constantly agitate fluid in the wells 6 and 7 so that more pronounced odors are given off from the said disinfecting fluid. Over said conical chamber is concentrically placed an outer cylindrical chamber 15 having its lower end at 16 suitably riveted or fixed to the lower end portion of said conical chamber so as to form a receptacle or well 17 for containing a suitable disinfecting fluid, the top of this outer chamber being coned at 18 and open at the top at 19 and provided with a similar and annular fluid containing cap 19 having an annular well 20 for receiving a suitable disinfectant, and like the cap 4 is supported on and clear of the top 19 of the outer chamber 15 by similar legs 21 which are bolted or otherwise detachably connected to the conical top 18. The legs 5 and 21 are fixed at 22 and 23 to their respective caps which latter are suitably'shaped as shown. The inner diameter of the annular well 20 at 24 is larger than the diameter of the opening at 19, and the inner diameter of the annular well 6 at 25 is larger thanthe opening 3 so that the fumes from sewer or the like are of the conical chamber 1 for bolting this conical chamber into the annular well 29 which is filled with water thus making an air-tight joint so that the draft or fumes from the sewer or the like passes up through the conical chamber 1 through the opening 27 and out at the top 3 into the cap 4 and into the outer cylindrical chamber 15 and thence through the opening 19 into the cap 19' and thence into the atmosphere through the openings 28, and at the same time this draft of foul or impure air is amalgamated or mixed with the odors given off from the disinfectants contained in the said annular wells and the receptacle or well 17 so that the gases reaching the atmosphere are rid of objectionable smells which are a source of danger to the public health. The hanger or container 26 rests in the man-hole or ventilator of the sewer or the like, and over such may be positioned at 32 the usual and known type of man-hole grating so that infiowing surface Water reaches and overflows the annular well 29 in the bottom of said container whence thewater flows over the top of this well at 33 into the sewer; or the like through the opening 27. The fan like blades 11 and 12 are suitably fixed at 34 to the end of the shaft or spindle 10 by bolting thereto or by riveting to such. Adjacent to or near to the annular well 20 is a filling or inspection hole 35 which is adjustably covered by means of a suitable cover such as 36 which may be hinged to the cap 19 or may be slidably fitted thereto as a panel over the inspection hole 35. A similar cover 37 is fitted over an inspection hole.38 in the cap 4, and a similar cover 39 is fitted over an inspection hole 40 in the conical chamber 1 above the disinfectant in the well or receptacle 17, and about opposite the cover 39 a similar cover 41 is fitted over themspection hole 42; and above the annular well 7 a similar cover 43 is fitted over the inspection hole 44, all of the covers and inspection' holes including suchshownat 47 in the coned top 18 being arranged so that the apparatus may be-inspeeted and the wells or, receptacles filled when desired. The cross-piece or supporting bracket 9 in which is centrally and vertically positioned the shaft 10, is suitably fixed at 45 insideof and about intermediate of the height of the inner conical chamber 1 by means of riveting thereto or by other suitable means. i

In combination With my said apparatus, I may use any suitable disinfectants or disinfecting fluids for the purposes set forth; and the constructional details of the said apparatus may be slightly varied Without departing from the nature or scope of the invention.

The hanger or container 26 is preferably enlarged or shaped as shown at 32 for the purpose set forth. The sides of the open end 2 of the conical chamber 1 at 46 are recessed or notched out preferably as shown so that the surface Water may have an unrestricted fioW into the Well 9 and thence through the opening 27 into the sewer or the like.
